If you look at the pictures on the wall behind cool chick on the phone in the bedroom, you can spot one of the digital artefacts the colorists inserted into the colorized version. The framed picture of the man and woman is not part of the original film. I presume it to be a snapshot of someone at the colorization lab, and it does not appear in the shot of the wall before or after this.
I added a shot from the B&W DVD and it sure is a different picture.
